death

[deth] the cessation of all physical and chemical processes that invariably occurs in all living organisms. (See also dying.) There is at present no standardized diagnosis of clinical death or precise definition of human death. The most widely known and commonly accepted means of determining death evolved from several medical conferences held in the late 1960s for the purpose of defining coma" >irreversible coma or nonfunctioning brain as a new criterion for death. The indications of deep irreversible coma (or death" >brain death) are (1) absolute unresponsiveness to externally applied stimuli; (2) cessation of movement and breathing, including no spontaneous breathing for three minutes after an artificial respirator has been turned off; and (3) complete absence of cephalic reflexes. The pupils of the eyes must be dilated and unresponsive to direct light.
Use of the electroencephalogram is also recommended as being of value in confirmation of irreversible coma or death. If there is a flat electroencephalographic reading at the time of apparent death and a second flat reading 24 hours later, then the patient may be declared dead.
There are two exceptions to the above criteria. These are in regard to patients exhibiting marked hypothermia (body temperature below 32.2°C), and those suffering from severe central nervous system depression as a result of drug overdose.
It is recognized that the above criteria are limited in that the notion of irreversibility is not readily agreed upon and may take on new meaning as medical technology advances. The criteria are especially helpful as complements to the traditional criteria of absence of heart beat and lack of spontaneous respiration as indications of death.
In 1981, a Presidential Commission for the Study of Ethical Problems in Medicine and Biomedical and Behavioral Research strongly recommended that all of the United States recognize the cessation of brain function as a definition of death, even in cases in which life-support systems could maintain respiratory and circulatory functions by artificial means.activation-induced cell death (AICD) recognition and deletion of T lymphocytes that have been activated and so induced to proliferate. T lymphocytes are activated when a foreign agent is perceived, and AICD thereby prevents them from overgrowth. It is particularly important for regulation of lymphocytes that recognize self antigens.black death bubonic plague; see plague.brain death (cerebral death) see brain death.clinical death the absence of heart beat (no pulse can be felt) and cessation of breathing.cot death (crib death) sudden infant death syndrome (SIDS).programmed cell death the theory that particular cells are programmed to die at specific sites and at specific stages of development.

death

(deth), The cessation of life. In lower multicellular organisms, death is a gradual process at the cellular level, because tissues vary in their ability to withstand deprivation of oxygen; in higher organisms, a cessation of integrated tissue and organ functions; in humans, manifested by the loss of heartbeat, by the absence of spontaneous breathing, and by cerebral death. Synonym(s): mors [A.S. dēath]

(deth) The irreversible cessation of life. In lower multicellular organisms, death is a gradual process at the cellular level, because tissues vary in their ability to withstand deprivation of oxygen; in higher organisms, a cessation of vital tissue and organ functions; in humans, manifested by the loss of heartbeat (i.e., asystole), absence of spontaneous breathing, and cessation of the brain's electrical activity.
